Alternative Energy

I NOW use alternative energy (check one that best applies to your situation). I I As my only power source Q As my primary power source I I As my backup power source O As a recreational power source (RVs etc.) I want to use alternative energy in the FUTURE (check one that best applies to your situation). I I As my only power source Q As my primary power source I I As my backup power source O As a recreational power source (RVs etc.) My site has the following alternative energy potentials (check...

3733 Kenora Dr., Spring Valley, California 92077 (619) 460-3930 showed there wasn't much to be gained by changing the shape of such a small wheel. However, the generators used so far had efficiencies in the 50 range or less. They also had electric field coils which made for easy adjustment of the output but also took part of the output to operate. It looked like the use of a permanent-magnet (PM) field would be a help and could make operation at very low-heads feasible. Yes, DC motors with PM...

The efficiency of small transformers even though they are designed to work at 60 Hz. Now the system has an efficiency of around 21 (36 Watts 170 Watts) using the power available at the nozzle as the starting point. Three Amperes in a 12 VDC system doesn't sound like much. But this is sufficient to run the lights, a small fridge (Koolatron) and a tape player-radio. My house is small and so are my needs. There was sometimes even extra power and I could run Christmas lights or leave on things just...

He choice of an engine driven generator, or generator as I will refer to it here, is one of the most important choices those considering alternative power can make. You might say to yourself, I have chosen wind, water or photovoltaics as my alternative power source. What do I need a generator for Well, that's what we are here to talk about. The generator has been the backbone of home power generation since the early 1900's. Many farms, ranches, and homes were modernized by the addition of only...

An Economics Approach to Solar Power See why and howphotovoltaics can save you money in yoursystem. All swell details such as initial cost, payback time, &amp operating cost are revealed. Come see what PVs can do for you. In the coming months we will be talking about a wide variety of topics relating to solar generated electricity the PVs themselves, trackers, mounting racks, controllers, instrumentation, and how the PVs fit into the entire alternative energy system. This first solar article is...

In 1970, we realized that our dreams depended on cheap land. The only desirable property we could afford was in the outback. Everything was many miles down a rough dirt road and far from civilized conveniences such as electricity. The 40 acres we finally bought is 12 miles from the nearest paved road, telephone, or commercial electrical power. We were ready to do without. This is not, however, an account of doing without-- it is a story of having one's cake and eating it too. We solved the...

For many people the idea of producing household electrical power from a wind turbine is a romantic notion, a dream that rarely becomes a reality. Still for others, especially those living far from an electrical line or experiencing outrageous utility bills, it becomes a necessity. There are thousands of homes across the country now being powered by a wind turbine or combination of wind and other alternative electrical power inputs. Each installation's success or failure depends heavily on...

By Alan Trautman amp Richard Perez Appliances are why we want the wonderful power of electricity. The most universal electric appliance is lighting. This article begins a discussion of efficient, reliable lighting appliances for alternative energy systems. Read ahead for the facts of this illuminating matter. Welcome to the first column about appliances and alternative energy systems. In the coming months we will be discussing a myriad of appliances and their application in alternative energy...
